Angular 卡在8个角度的错误循环中

看来，我陷入了一个无限的角度误差循环中。我将本地angular版本从1.7.0更新为angular 8。我的全局角度版本已经是8了。在将angular版本更新为8之后，我运行了下面的命令

 ng serve 

我的错误是

"The serve command requires to be run in an Angular project, but a project definition could not be found"

`"Repository is not clean.  Please commit or stash any changes before updating.".`

"Repository is not clean.  Please commit or stash any changes before updating" 

"The serve command requires to be run in an Angular project, but a project definition could not be found."

在谷歌搜索了这个问题后，我在终端窗口中运行了这个命令

"ng update @angular/cli --migrate-only --from=1.7.0". 

在运行这个命令之后，我得到了这样一个错误

"The serve command requires to be run in an Angular project, but a project definition could not be found"

`"Repository is not clean.  Please commit or stash any changes before updating.".`

"Repository is not clean.  Please commit or stash any changes before updating" 

"The serve command requires to be run in an Angular project, but a project definition could not be found."

为了修复错误，我运行了以下命令

 ng update --all --force.

我又犯了一个错误，说

"The serve command requires to be run in an Angular project, but a project definition could not be found"

`"Repository is not clean.  Please commit or stash any changes before updating.".`

"Repository is not clean.  Please commit or stash any changes before updating" 

"The serve command requires to be run in an Angular project, but a project definition could not be found."

所以我运行了这个命令

ng update -all --force --allow-dirty. 

当我运行上述命令时，我收到以下消息：

Repository is not clean.  Update changes will be mixed with pre-existing changes.
Using package manager: 'npm'
Collecting installed dependencies...
Found 35 dependencies.
Package '-l' is not a dependency.

在这之后，我又这样做了

ng serve 

我又犯了一个错误，说

"The serve command requires to be run in an Angular project, but a project definition could not be found"

`"Repository is not clean.  Please commit or stash any changes before updating.".`

"Repository is not clean.  Please commit or stash any changes before updating" 

"The serve command requires to be run in an Angular project, but a project definition could not be found."

我愿意回到angular版本7，但不确定这是否有帮助。下面是我在做ng时看到的图像——版本

在此方面的任何帮助都将不胜感激。

有一个命令允许绕过git状态检查

ng update @angular/cli --allow-dirty

更新正在检查未提交的文件，并且失败了，因为如果更新在没有清除状态的情况下继续进行，可能会给自己带来一些麻烦。 即将到来的日期将只检查角度文件

否则，请隐藏或提交您的工作，然后再次运行update命令。

您正在从1.7.0版更新到8版或从7版更新到8版？mate您是否确定您在服务时处于您的角度项目中？请检查终端-->cd yourAngularProjectPath/中的路径，然后尝试从1.7.0到8进行ng servefrom。我的全局版本已经是8了，但是我的本地版本显示了1.7.0。我不知道为什么它会显示这个版本，但当我制作ng-version时，我得到了1.7.0。
